Villanueva had a lot of success as a starter in the minors, but has spent most of his big-league career as a long reliever and has been mediocre when called on to make spot starts. He started 16 times for Toronto in 2012, struggling to keep the ball in the ballpark while posting a 4.50 ERA, but also had an 86/25 K/BB in 92 innings. If given a chance to build up his arm strength as a full-time starter at age 29 he could provide nice value.
